MIAMI (CBSMiami) – If you’ve ever tried to install a car seat, you know how frustrating it can be for even the most seasoned parent. According to the Insurance Institute of Highway Safety, there’s a reason for this, cars aren’t being set up properly to make car seat installation easy.

The IIHS focused on the system known as Lower Anchors and Tethers for Children, or LATCH. The system was originally designed with standard hardware to make car seat installation easier. Even with the LATCH system, the installation of a car seat is still problematic.

“Installing a child restraint isn’t always as simple as a couple of clicks and you’re done,” says Anne McCartt, the Institute’s senior vice president for research and one of the report’s authors. “Sometimes parents blame themselves when they struggle with LATCH, but oftentimes the problem lies with the vehicle, not the user.”

The IIHS found that only seven vehicles out of 98 analyzed had a LATCH system in the middle of a second-row seat, which is the safest place for children to travel. In addition, the lower anchors for the system were visible on just 36 of the 98 cars studied.

IIHS researchers looked at three factors in making their determinations: Depth, Clearance, and Force. Depth referred to how deep in the seat the anchors were. Clearance refers to nothing obstructing access to the anchors. Researchers said force was based on using less than 40 pounds of force during installation.

Several 20111 models did meet all of the easy-installation criteria including:
